I'm starting to think you are all much smarter than me... So, when I imagine I were my Lavellan... I meet that guy, looks just like your ordinary monk from next door, tells me he's travelled the Fade and seen the most curious things, studied a lot, went many different places... never really had many friends, too, thus having a lot of time for doing all that... discussed with demons and spirits, just sucking up every bit of knowledge he could possibly come across. Never heard of such people before, but then again, I have also never met a movie star or a Roman legionnaire and still know they exist(ed). Now, that guy has seen that orb somewhere, it is Elven, old, somehow magical. Much more he does not know though. It must have been what opened the breach, because what else could have had such power? And so on and so on, Skyhold, blah.
So, honestly, my first thought would not be "Gosh, he must be an Old God!" I might rather think "Kind of nerdy... damn, I wish I had such knowledge. Certainly impressive at every party or game show". My boyfriend can tell me a lot of things each day that I did not know, simply because I never cared to learn about them while he did. But it has never occurred to me that he might be an Old.... wait.
Seriously, was I really the only one who had been surprised by the ending after the first playthrough? Did you all see that coming?
I tried my best to keep away from spoilers...but by the fade kiss scene I thought he must be a somniari, and then I suspected he was possessed by a pride demon. I also suspected from the very first chat in Haven that he might have been involved in the conclave explosion somehow. There's just something about the way he responds to the " you can trust me" flirt. And the whole bit about "pretenses". Then somewhere along the way I got accidentally spoiled that he leaves/breaks up with you...sorta glad I was prepared for that one.
Didn't see the ancient elf or dread wolf coming though. Which was awesome because in DAO and DA2, I thought Fen'Harel was the most badass elven god, and roleplayed my Hawke as being fascinated by Merrill's story about him. I still kinda can't believe they let us romance him. Lol.
Anyway I roleplayed my Lavellen as definitely suspecting something, and knew he had secrets, but hoped he would eventually tell her when he was ready, so she didn't push. I figure she didn't trust the humans/chantry folks at first either and believed Solas really did want to help...plus he seemed to be the only one who really knew anything about the mark, so whatever he did before, she didn't care at that point.
Oh and I think I expected him to be a lot more pacifist, based on how he was described pre-release. So when he went after the mages in a rage in his personal quest I was surprised by that too.
